\n" );
document.write( "- 1 is a ROOT, which means that x = - 1.
\n" );
document.write( "Setting this equation equal to 0, we get: x + 1 = 0, which means that x + 1 is a FACTOR of this polynomial.
\n" );
document.write( "Do you now see where x + 1 came from?
\n" );
document.write( "An easy- maybe not the best - method to solve this is the method that Tutor ewatrrr posted, which is long-division of a polynomial.
\n" );
document.write( "Synthetic division is another easy method if you're familiar with that topic.
\n" );
document.write( "Pay no attention to the other person's, if you want to make live easier for yourself!. \n" );
document.write( "

\n" );
